Tried this in 10.2 Campus editing, had some difficulty getting it to work.
I had everything running on my laptop. Sqlserver express database with LGIM, SDE, and arcmap.
Added buildingfloorPlanLine records to the feature class.
Attribute values for floor, buildingkey, and floorkey were getting the values from the wrong floor.
Verified Definition Query for BuildingFloor layer was correct.
Checked DynamicValue table for correct ValueInfo entry "BuildingFloor(Layer)|Floor" for TableName BuildignFloorplanLine.
Reconciled and posted edit version.
Issue continued.
Shutdown laptop left for the evening.
Rebooted laptop the next morning.
Now it works.
